interop_support.js breaks unknown HTML elements

The bug is on line 117 -- it should be outside the if block. It looks like that "hook" breaks the handling of unknown HTML elements, which would explain the change in behavior for . This patch fixes the issue:

     });
   }

I'll upload a CL with a test to reproduce.
